The Indian diplomat whose arrest and strip-searching in New York caused a major rift between India and the United States was indicted for visa fraud on Thursday, and the U.S. government immediately asked her to leave the country. A U.S. government official said Washington accepted a request by India to accredit the diplomat, Devyani Khobragade, at the United Nations and then asked New Delhi to waive the diplomatic immunity that status conferred. India denied the request, leading Washington to ask for her departure, the official said.
